Serial No. 652,431.

To all whom it may concern:

Be it known that I, MARTIN IilALFPENNY,

flcitizen of the United States, residing at Pontiac, county of Oakland, State of Michigan, have invented a certain new and useful IIHIHOVQllltBllt in Dcmountable Rims for Automobile or other Wheels, and declare the following to be a full, clear. and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being bad to the accompanying; drawings, which form a part of this specification. Y

My invention relates to an improvement in demountable rims for automobile or other vehicle wheels, shown in the accompanying drawings and more partit'zularly pointed out in the following specification and claim.

The object of my invention is to provide a quickly dcmountable rim adapted to carry an auxiliary pneumatic tire which may be substituted for the tire and rim in use in the event of a puncture,-the construction being such that the rim installed may be forced oh the felly throu h the action of the attaching bolts by which the rim is secured thereto.

In the drawings accom anying this specificationz-Figure 1 is a m mentary crosssectional view through the telly and rim of a wheel, showing one of the several attachin bolts employed to secure the rim to the folly. Fig. 2 is a similar view indicating the rim being forced from the folly through the action of the flange on the attaching .bolt. Fig. 3 is a fragmentary perspective view of the removable rim. and. one of the bolt supporting angle plates, with ,parts brokenaway and 1n section to more clearly disclose the construction. Fig. 4 1s a fragmentaryperspectivo'view of a metallic rim rigidly secured to the wooden folly, showing one of the brackets attached thereto for supporting the outer ed e of the removable rim. Fig.5 is a side e evation of a wheel with the removable rim in position.

Referring now to the letters of reference placed n on the drawing is the wooden fe 1y. Bthe spokes of a'wheel.

(l is a metallic rim secured to the wooden folly, having upturned flanges c,

D is a removable rim to the under-face of which are riveted or other-use secured a plurality of angle plates D preferably spaced cquidistant-ly throughout. the rim.

A plurality of brackets E, are respectively set in mortises formed in the metallic rim (7 for their reception, being secured to the rim by rivets or screws v. (be down ardly projecting lug c of the ln'acket bcingtapped to receive a bolt l supported in the dcpcndin flange oil the angle plate l). The bolt F 18 provided with a flange lodged between the cup-slnqnal plate. G, and the depending flange oi the angle plate D, to which the plate (it is engaged. The projecting end c of the brackets l evtends through a recess formed in the thin; I c of the rim C and is upwardly inclined to pro vide a bearing surface for the removable rim when the latter is forced into position. over the telly. The flange 0 is cut away at c to ermit the entry of the web of the angle pl to D, secured to the underside of the removable rim.

Having denoted the several parts by reference letters, the construction and operation of the device will be readily understood.

To engage the removable rim with the wheel, the rim is first brought into )osiition to encircle the telly, the bolts are then engaged with the tapped lug of the several supporting brackets by the use of a brace wrench or other suitable tool; thereby forcing the rim into position u on the, telly.

To remove the. rim, the olts are rotated in the reverse order to that just described which action due to the projecting flanges f of the bolt bearing against the cup-shaped 'lates G, forces the removable rim from the oily, overcoming any tendency these may be of the rim binlding thereon.

Having thus described my invention, what I claim is:--

In a wheel, a fixed rim, brackets secured to the fixed rim having inwardly projecting tapped lugs set mortises formed in the rim andkeaoh providedwith a projecting finger c-urvml outwardly adaplml to bear against and suppnrl the outer edge of a 1'( movable rim, the renmvable rim, angle plains secured in the removable rim, a bolt supported in each 01" the angle platos adapt ml to engage the tapped lugs of the brackets, said bolls each provided with an outwardly projecting flange, and a plurality of plates' pierced for the passage of thc boltv secured to the respective angle plates to house the 10 flange of the bolt btitwcen Said plates a d the angle plates. I y In testimony whereof, 1 sign this specification in the presence oftwn witnesses.
